Tanzanite

Tanzanite, is it blue with purple highlights, or purple with subtle burgundy, or perhaps purple with deeper violet hues? The answer to that question can be “yes” to all those variations because Tanzanite is one of the most remarkable gemstones of all. The molecular makeup of Tanzanite causes light shining on it to be divided into different wavelengths, producing 3 distinct tone families, with many shades within each. This member of the zoisite mineral family was only discovered in 1967, and has gained a wide following of admirers in its relatively short history in the jewelry market. It is mined only in Tanzania, in the foothills of famed Mount Kilimanjaro, and displays a breadth of natural color few gems can boast. Tanzanite plays whimsical games with the light and offers the admirer a variety of looks throughout each day. Softer light brings out the deeper, richer tones, while the more vibrant, cerulean blues and radiant purples make their appearance in brighter light.

Grading Tanzanite

Tanzanite is evaluated using similar criteria to rubies, though because it has been available for a relatively short period of time, there are no hard and fast rules, especially when it comes to color. Many admirers think it ought to stay that way, so each lover of beautiful gems can make up their own mind about which shade they find the most appealing. Still, stones with the deepest color, be it deep sea blue, burgundy to match the wine, or a violet-tinged purple, will bring the most praise and the highest price. Clarity of the tanzanite is important, too, and most gems show exceptional clarity to the naked eye, with very few impurities in the stone. Carat weight is also considered, with many stones being found that offer well over 1 carat in weight. Tanzanite is making new fans with each passing year, and finding a central or complementary place in fine jewelry of all kinds. It holds its own when matched with diamonds, rubies, or emeralds. Surround it with pearls and the result will take your breath away.
